  • Since April, 1957, 200 White Leghorn and 100 Newhampshire had been brought to the poultry farm of our college from Songwhan National Breeding Station. The looses due to avian tuberculosis were 67 chickens by June, 1959. Thirteen of them were examined histopathologically. Grayish white tuberculous nodules varying in size were recognized in the liver, spleen, bone marrow, and intestine of all affected birds. The heart rind testis were involved in each case, and pulmonary tuberculosis which, unlike in mammals, was kown to be rarely encountered in birds was observed in two cases. One case showed amyloid like degeneration in hepatic cell cords of the liver, glomerular tufts and collecting ducts of the kidney. Lesions in the spleen presented typical Sago spleen. Sections from the liver, spleen, intestine, and lungs were stained by Ziel-Neelsen stain. Acid Fast stained bacilli were found embeded in the cytoplasm of epithlioid cells and foreign-body giant cells.

  • Natural products are important sources for drug development because they have a wide variety of useful biological properties. Angelica gigas Nakai (AGN) has been used as an herbal medicine. The present study was designed to evaluate the immune-enhancing effect of AGN in the cyclophosphamide (CP) induced immune-suppressed mice. As the result, we found that CP induced the reductions of body ratio, spleen weights, hematopoietic parameter and cytokine productions in mice. However, AGN recovered immunosuppression-mediated decreased body ratio, spleen and thymus weights as well as regulation of hematopoietic parameter including white blood cell, lymphocyte, and neutrophil. According to histological study, AGN regenerated on CP-mediated injured spleen. Moreover, AGN increased the CP-induced reduction of cytokine expression in spleen tissue. Collectively, the findings provide experimental evidence that AGN may be a candidate for health-improving herbs.

  • Background: Hematopoiesis is the production of blood cells from hematopoietic stem cells (HSCs) that reside in the bone marrow. Cyclophosphamide (CTX) is a chemotherapy drug that suppresses the immune system. Korean Red Ginseng (KRG) and Colla corii asini (CCA) have been traditionally used for boosting the immune system. Methods: HSCs in the bone marrow, and immune cell subtype in splenocytes, PBMCs, and thymocytes were investigated. Serum levels of hematopoietic-related markers were analyzed using ELISA. Protein expression in spleen tissue was analyzed using western blot analysis. Hematoxylin & eosin staining in the femurs of mice were also conducted. Results: The combination of KRG and CCA with a ratio of 3:2 increased HSCs, CD3 and CD8+ T cells in the circulation, and CD3 T cells in the spleen. A ratio of 2:3 (KRG:CCA) increased the thymic regulatory T cells and recovered the CD3 T cells in the spleen and circulation while recovering proteins in the JAK-STAT pathway in the spleen. Overall, blood cell population and differentiating factors vital for cell differentiation were also significantly recovered by all combinations especially in ratios of 3:2 and 2:3. Conclusion: A ratio of 3:2 (KRG:CCA) is the most ideal combination as it recovered the HSC population in the bone marrow of mice.

  • Effects of red ginseng acidic polysaccharides (RGAP) on immune system were studied. The proliferation of spleen cells was induced by RGAP treatment per se. Cotreatment of lipopolysaccharide $(100\;{\mu}g/ml)$ or concanavalin A $(1\;{\mu}g/ml)$ with RGAP further stimulated the spleen cell proliferation. BALB/c mice treated with RGAP showed a slight splenic hyperplasia and increased antibody forming cell response to sheep red blood cells. Flow cytometry analysis revealed an influx of macrophages in the mice treated with RGAP.

  • 감성돔 (Acanthopagrus schlegeli)의 비장에서 주화세포인 BSBS를 확립하고 세포의 특성을 검사하였다. BSBS세포는 60회 이상의 계대배양이 가능하였고 형태학적으로는 상피성 세포였다. 세포는 20℃, 10%의 FBS가 든 L-15배지에서 배양하는 조건에서 잘 자랐다. BSBS세포는 해양버나바이러스 (MABV Y-6), 잉어의 봄바이러스병바이러스 (SVCV), 넙치의 랍도바이스 (HIRRV)와 연어바이러스 (CSV)를 접종했을 때 세포변성효과가 나타났다. 새로 확립된 주화세포는 앞으로 많은 바이러스병의 연구에 유용하게 사용할 수 있을 것으로 생각된다.

  • 1. Objectives: The purpose of this study is to investigate the effect of Suhwagije-tang(SGT) distillate on the immune activity of spleen cells of aged SD rats. 2. Methods: We used 10, 50, 72 weeks old SD rats in this study. Spleen cells from SD rats were stimulated with ConA and treated with 1% Vitamin C(Vit.C) or Suhwagijetang distillate(SGT). After 24 hours, the concentrations of IL-2, IL-4, IL-10, IFN-${\gamma}$ in the cell culture supernatant were measured by ELISA. 3. Results and Conclusions 1) At all concentration of SGT distillate, survival rates of liver cells were higher than the control group. In addition, 50% SGT distillate group's cell survival rates were significantly higher than other groups. 2) In 10 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group, Vit.C group. In 52 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group. 3) In 10, 52 weeks SD rats(SGT group), the concentration of IL-4 significantly decreased in comparison with ConA group. 4) In 10 weeks SD rats(SGT group), the concentration of IL-10 significantly decreased in comparison with ConA group. And in 72 weeks SD rats(SGT group), the concentration of IL-10 significantly increased in comparison with Vit.C group. 5) In 52, 72 weeks SD rats(SGT group), the concentration of IFN-${\gamma}$ significantly decreased in comparison with 10 weeks SD rats(SGT group). These results suggest that Suhwagije-tang(SGT) distillate has the effect of increasing the immune activity of spleen cells of aged SD rats.

  • Objectives: The object of this study was to observe antitumor, anticachexia and immunomodulatory effects of Shipyeukmiyeugi-eum(SYM) on human breast cancer cell, MCF-7, xenograft Balb/c nu-nu nude mice. Methods: Three different dosages of SYM-125, 250 and 500 mg/kg were orally administered once a day for 28 days from 11 days after tumor cell inoculation, and the changes on the body weights, tumor volume and weights, weights of spleen and popliteal lymph node and epididymal fat, serum IL-6 and IFN-${\gamma}$ levels, NK cell and peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were observed. In addition, histopathological observations of apoptotic cell, spleen, popliteal lymph node and cervical brown adipose were also detected. The results were compared with a potent cytotoxic estrogen receptor antagonist, Tamoxifen 20 mg/kg treated mice. Results: Tumor volumes and weights were decreased without cytotoxic effects on the both MCF-7 and MCF-10A cells as results of all three different dosages of SYM treatment. And weights of body, spleen, popliteal lymph node, epididymal fat, serum IFN-${\gamma}$, NK cell, peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were increased with decrease of serum IL-6. At histopathological observations, apoptotic tumor cells, spleen, popliteal lymph node and cervical brown adipose tissue were increased. That means tumor-related immunosuppress and cachexia were markedly inhibited by SYM treatment as compared with tumor-bearing mice. On the other hand, Tamoxifen showed marked cytotoxic effects against MCF-7 and MCF-10A, decreases of tumor volume and weights, and increases of apoptotic tumor cells and related decreases of tumor cell volumes, but tamoxifen markedly deteriorated the tumor-related immune-suppress and cachexia. Conclusions: The results obtained in this study suggest that SYM showed favorable anticancer effects and anticachexic effects on the MCF-7 cell xenograft through immunomodulatory effects. SYM did not induce any cytotoxic effects against both normal and cancer cells.

  • Objective : The purpose of this study is to investigate the anti-oxidative effect of Jeokbaekhaogwanjoong-tang (JGT) distillate in spleen cells of aged rats.Methods : This experiment was performed using spleen cells of 10w, 52w, 72w old sprague dawley (SD) rats. The spleen cells of 10, 52, 72 weeks old rats were divided into three groups; DW group, Vit. C group, and JGT group. The cells of DW group were treated with distilled water. The cells of Vit.C group were treated with Vitamin C. And the cells of JGT group were treated with JGT distillate. After the treatment of DW, Vit.C, and JGT, the levels of superoxide dismutase (SOD), glutathione (GSH), nitric oxide (NO) and lipid peroxidation (MDA) were measured.Results : In the spleen cells of 72 weeks old rats, SOD activity was significantly increased in the JGT group compared to those in the DW group and the Vit.C group. In the spleen cells of 52 weeks old rats, GSH activity was significantly increased in the JGT group compared to the Vit.C group, and NO concentration was significantly decreased in the JGT group compared to the DW group and the Vit.C group. MDA concentration was not changed significantly in any cell groups by the treatment of JGT distillate.Conclusions : Jeokbaekhaogwanjoong-tang (JGT) distillate may have an anti-oxidative effects in the spleen cells of aged rats. Further investigation is needed for the anti-aging effect of JGT.

  • To investigate the effects of ESWTT on rheumatoid arthritis in collagen-induced arthritis mice model, the animals were orally administrated with the extract following by analyzing the changes of lymphocyte composition in spleen with flow cytometry. These results suggest as follows; 1. ESWTT decreased the total cell number of spleen at 400 and 200 mg/kg about 41% and 32%, respectively. 2. ESWTT reduced the number of CD19+ cells in spleen at 400 and 200 mg/kg about 51% and 46%, respectively. 3. ESWTT down-regulated the number spleen CD3+ cells approximately 26% at 400 mg/kg-treated group. 4. ESWTT decreased the number of CD3+/CD69+ cells in spleen at 400 and 200 mg/kg about 79% and 76%, respectively. 5. ESWTT reduced the number of CD4+ and CD8+ cells in spleen, however, the results were not significant. 6. ESWTT decreased the number of CD4+/CD25+ cells in spleen at 400 and 200 mg/kg about 60% and 56%, respectively. Taken together these results, ESWTT has an efficacy on rheumatoid arthritis through inhibiting the proliferation of lymphocytes such as B and T cells.
